HP Continuous Access P6000/EVA 3-site configurations
This section describes the following HP Continuous Access P6000/EVA 3-site configurations:
•
HP Continuous Access EVA 3-site configuration with four gateways (page 17)
•
HP Continuous Access EVA 3-site configuration with six gateways (page 17)
•
HP Continuous Access EVA 3-site configuration with eight gateways (page 19)
•
(page 20)
The first three configurations provide a fan-in or fan-out relationship between the sites. The fourth
configuration provides a peer-to-peer relationship between all sites.
Figure 14 (page 17) shows connectivity for three sites using four mpx110 gateways, which
implements the minimum-level and lowest-cost connectivity for a 3-site configuration. Figure 15 (page
18) shows additional connectivity and redundancy using six mpx110 gateways. Figure 16 (page
19) shows the highest level of 3-site connectivity using eight mpx110 gateways.
Figure 17 (page 20) is similar to Figure 15 (page 18) , with additional connectivity to allow for
replication between Site 2 and Site 3.
The following configuration rules apply to Figure 14 (page 17) through Figure 16 (page 19)
(fan-in/fan-out relationships):
•
For Site 1, Site 2 or Site 3 can function as the remote site.
•
For Site 2 or Site 3, Site 1 can function as the remote site.
•
Replication between Site 2 and Site 3 is not supported.
The following configuration rules apply to Figure 17 (page 20) (peer-to-peer relationship):
•
For Site 1, Site 2 or Site 3 can function as the remote site.
•
For Site 2, Site 1 or Site 3 can function as the remote site.
•
For Site 3, Site 1 or Site 2 can function as the remote site.
3-site configuration with four mpx110 gateways
The configuration shown in Figure 14 (page 17) provides long-distance link redundancy between
all three sites.
Figure 14 HP Continuous Access P6000/EVA 3-site configuration with four mpx110 gateways
3-site configuration with six mpx110 gateways
The configuration shown in Figure 15 (page 18) provides the same long-distance link redundancy
as the configuration shown in Figure 14 (page 17) , with the addition of redundant mpx110
gateways at sites 2 and 3.
